                                                           from it. This interaction is harmful to

             The Importance of Interaction Among

             Living Things to the Ecosystem

                              Why do living things need to interact with each other?

             Interaction in the form of competition and prey-predator can control
             the population of organisms in a habitat.

                                                           plantations can
                                                           be controlled with
                                                           the presence of
                                                           predators such as
                                                           owls.                       owl

             The living things in an ecosystem interact with one another
             to ensure the survival of their species.

               In a pond, the large fish depend on the small fish to ensure the
               survival of their species. How do the small fish and the tadpoles
               ensure the survival of their species?
